SORT Operator
SORT Operator (for Beginners)
Summary
For extensive information, go through the SORT Operator for Experienced
SORT operator sorts a dataset into up to 10 output datasets.
Syntax -

Required Operands
- FROM - FROM parameter specifies ddname of the input file.
- JKFROM - JKFORM is used for a JOIN KEYS application.
- USING - USING operand specifies the first 4-characters of the ddname (xxxxCNTL) for the DFSORT control statement file.
Optional Operands
- TO - TO operand specifies 1 to 10 ddnames of output files.
- VSAMTYPE - VSAMTYPE operand specifies the record format for a VSAM input file (F or V).
Example -
Scenario - Sort the employee records based on employee name (15 character length from 6th position).
INPUT - MATEPK.INPUT.PSFILE

Explaining Solution -
- INDD - Specifies the ddname for input file.
- OUTDD - Specifies the ddname for output file.
- TOOLIN DD * - Specifies the ICETOOL statements for DFSORT.
- TOOLMSG - Specifies where to write the ICETOOL processing messages.
- DFSMSG - Specifies where to write the DFSORT processing messages.
- CTL1CNTL DD * - Specifies the DFSORT statements for processing.
- SORT FROM(INDD) TO(OUTDD) USING(CTL1) - Sorts the indd records and copies to OUTDD based on the selection criteria in CTL1.
- SORT FIELDS=(50,2,CH,A) - Sorts the records in ascending order based on the data of length 15 from 6th position.
